This study presents the first data set of sulfurisotope compositions of primary Ru-Os sulfides, represented by laurite (RuS2) - erlichmanite (OsS2) series, within a primary platinum-group mineral (PGM) assemblage derived from the Verkh-Neivinsky dunite-harzburgite massif, a typical example of the mantle ophiolite association at the Middle Urals. The S-isotope signatures of Ru-Os sulfides studied are consistent with derivation of the ore material from a mantle source for Ru-Os sulfides.
